Enzanisa silicon-based optoectronicIQ ModulatorKune yakakwirira-yekumhanyisa yekukurukurirana
Kuwedzera Kunodiwa Kwemakakwira Data Tate uye More Energy Transcerivers mune data nzvimbo dzakatenderedza kusimudzira kweKumusoro-kuitaOptical Modulators. Silicon Yakavakirwa Optoelectronic tekinoroji (Siph) yave iri chiratidzo chekubatanidza zvikamu zvakasiyana-siyana zvePotonics pane imwe chip, inogonesa mhinduro uye dzinodhura-dzinobhadhara. Chinyorwa ichi chichaongorora chinotakurika silicon IQ modulator zvichienderana neGesion eams, iyo inogona kushanda kune imwe nguva inosvika makumi manomwe nemashanu Gbaud.
Dhizaini dhizaini uye hunhu
Iyo yakakurudzirwa IQ modulator inogamuchira compact matatu ruoko chimiro, sezvakaratidzwa mumufananidzo 1 (a). Inoumbwa ne3 matatu eam uye matatu Thermo Optic phase shinda, inotora gadziriro yekudyidzana. Chiedza chekuisa chakabatanidzwa muChip kuburikidza nejista complam complet (GC) uye zvakakamurwa kuita nzira nhatu kuburikidza ne1 Mushure mekupfuura nemumhanzi uye phase shinda, iyo mwenje inodzoserwa neimwe 1
Mufananidzo 1: (a) microscopic mufananidzo weIQ modulator; . . (f) kutakura kutakura kumiririra pane iyo yakaoma ndege. Sezvinoratidzwa mumufananidzo 1 (b), Gesi eam ane huwandu hwakasiyana-optic bandwidth. Mufananidzo Mifananidzo 1 (c) uye 1 (d) zvichiratidza zvinongedzo kutsakatika chiyero (er) spectra pane dzakasiyana dc voltages uye kutapurirana kune mavheti e1555 Nanometers.
Sezvinoratidzwa nemufananidzo 1 (e), chinhu chikuru cheiyi dhizaini kugona kudzvinyirira vatakuri vepakati nekugadzirisa iyo yakabatanidzwa chikamu cheshuwa mukati meiyo yepakati ruoko. Musiyano wepakati pakati pematanda ekumusoro uye akaderera pane π / 2, anoshandiswa kuomarara tuning, nepo musiyano wepakati pakati peiyo yepakati ruoko ndi -3 π / 4. Uku kurongwa kunobvumira kukanganisa kwekuparadza kune mutakuri, sezvakaratidzwa mumhepo yakaoma yemufananidzo 1 (F).
Kuedza kuseta uye mhinduro
Iyo yakakwira-yekumhanyisa yekuedza yekuedza inoratidzwa mumufananidzo 2 (a). Anocherekedza macarforner Jenareta (Keyight M8194a) anoshandiswa seSignal Source, uye maviri 60 GHZ PhpEl RF Amplifiers (ine yakabatanidzwa bias tete) inoshandiswa sevatyairi veModulator. Iyo basas voltage yeGesi eam ndeye -2.5 v, uye chikamu chakafanana nzizi rf inoshandiswa kudzikisira chikamu chemagetsi chikamu pakati peiyo uye q chiteshi.
Mufananidzo wechipiri: Shandisa Caverce Online Cavity Cavity (ECL) ine mutsara wezana zana KHz, wavelength of 1555 nm, uye simba re12 DBM seye 12 DBM seyekutanga mutakuri. Mushure mekunyorwa, chiratidzo chechiratidzo chakamisikidzwa uchishandisa anErbium-Dided Filber Amplifier.
Pamugumo unogashira, Optical spectrum analyzer (OSA) monitors iyo signor spectrum uye inotakura kudzvinyirira, sezvakaratidzwa mumufananidzo 2 (B) yezhizha reGbaud. Shandisa polarization inosangana neanogamuchira anogamuchira zviratidzo, izvo zvine 90 degree Optical musiyano uye ina40 GHZ zvakaringana Photodiodes, uye yakabatana ne33 ghz, 80 GSA / s chaiyo-nguva oscilloscope (RTO) (Keyight Dsoz634a). Iyo yechipiri ecl sosi ine mutsara wegumi khz inoshandiswa seyunoshandiswa oscillator (lo). Nekuda kweiyo transmitter inoshanda pasi pemamiriro ezvinhu maviri emvura, chete maviri magetsi nzira inoshandiswa kuAnalog-ku-digital kutendeuka (Adc). Iyo data yakanyorwa pane rTO uye yakagadziriswa uchishandisa iyo Offline digital chiratidzo processor (DSP).
Sezvinoratidzwa mumufananidzo 2 (c), iyo IQ modlator yakaedzwa uchishandisa QPL modulation fomati kubva makumi mana Gbaud kusvika 75 Gbaud. Mhedzisiro yacho inoratidza kuti pasi pe7% yakaoma sarudzo mberi yekukanganisa kukanganisa (HD-FEC) mamiriro, chiyero chinogona kusvika 140 gb / s; Pasi pemamiriro e20% yakapfava sarudzo mberi yekukanganisa kururamisa (SD-fec), kumhanya kunogona kusvika 150 GB / s. Dhizaini yeboka remauto pa 70 Gbaud rinoratidzwa mumufananidzo 2 (D). Mhedzisiro yacho inogumira neOscilloscope bandwidth ye33 ghz, iyo yakaenzana neyakaenzana chiratidzo chebhavhu revanhu vangangoita makumi matanhatu nematanhatu.
Sezvinoratidzwa mumufananidzo 2 (b), iyo nhatu ruoko chimiro inogona kubatsira zvinobudirira kutakura vatakuri vane huwandu hwakareba kupfuura 30 db. Ichi chimiro hachina kuda kudzvinyirira kwakazara kweanotakura uye zvinogona zvakare kushandiswa mune vanogamuchira izvo zvinoda kutakura toni kuti dzoregedze masaini, akadai saKramer Krronig (KK) vanogamuchira. Iyo inotakura inogona kugadziridzwa kuburikidza neCentral ruoko chikamu chinotsvaira kuti uzadzise mutakuri wekutakura kuenda kune chikamu chebhandi (CSR).
Zvakanakira uye Zvikumbiro
Kuenzaniswa neNetsika Cache Machine Mohider Modulators (Mzm modulators) Uye imwe silicon-based optoelectronic iq modulators, iyo yakadhindwa silicon iq modulator ine akawanda zvakanakira. Chekutanga, iyo yakafanana nehukuru, kanopfuura kagumi madiki madiki pane IQ modulators zvichibvaMach Zehender Modulators. Kechipiri, iyo yakasimudzwa Electrode dhizaini haidi kushandiswa kweiyo terminal resters, nekudaro kuderedza kifaa yekushandisa uye simba pane zvishoma. Yetatu, iyo yekutakura Yekutakura Kukurukurirana inowedzera kuderedzwa kwesimba rekutapurirana, nekuwedzera kudzikisira kugona kwesimba.
Uye zvakare, iyo Optical bandwidth yeGesiE yakakura kwazvo (inopfuura makumi matatu Nanometer), kubvisa kudiwa kwemasangano ekudzora
Iyi compact uye inoshanda iyo modulator yakakodzera kwazvo kune inotevera-chizvarwa, uye diki conenttiver munzvimbo dze data, inogonesa huwandu hwekukurukurirana uye kuwedzera simba.
Iyo yekutakura yakachengetedzwa Silicon IQ modulator inoratidza yakanaka kuita, neyakagadziriswa data yeiyo kusvika ku150 GB / S Under 20% SD-FEC Mamiriro ezvinhu. Yake compact 3-ruoko chimiro chakavakirwa paGesi eam ine zvakanakira zvakanakira maererano netsoka, kugona kwesimba, uye kurongedza zvakareruka. Iyi modulator ine kugona kwekudzvinyirira kana kugadzirisa mutakuri wepamutemo uye inogona kuve yakabatanidzwa neine conent kuongororwa uye kk Zvinyorwa zvinoratidzwa zvinotakura kuzadziswa kwesanganiswa zvakanyanya uye zvinoshanda zvekutakura zvekutakura zvinosangana nekukura kwekukura kwekutaurirana kwakanyanya data mune data data uye mamwe minda.
